PB-676: remove duplicate YAML key from spec.

[adk-swisstopo]

As far as YAML is concerned, each key in a Map must be unique. The "example" Map has two keys named "title". This change removes one of the two duplicate keys.

An alternative fix would involve turning this into a list of examples. However the OpenAPI validator we use does not seem to support it at this time.

This seems unlikely to be related.

The test passed when I triggered the build again: https://eu-central-1.console.aws.amazon.com/codesuite/codebuild/974517877189/projects/service-stac/build/service-stac%3A7fcb0352-d239-485a-ad4a-4c059a690adf/
I haven't seen this fail in the last 80 iterations or so. Looks like a flaky test. I have opened PB-694.
